England striker would almost certainly have departed Old Trafford had Ferguson stayed

The constant theme through Sir Alex Ferguson’s autobiography is control.
During 26½ years as manager at Old Trafford, he operated on the basis that
“the minute a Manchester United ­player thought he was bigger than the
manager, he had to go”.

Ferguson, though, is no longer ­United’s manager. If he was, Wayne Rooney
would almost certainly have been sold this summer. Had Rooney and Chelsea
not encountered such firm resistance from David Moyes and the United
hierarchy, it is feasible that the chapter entitled Rooney might have
been explosive rather than merely ­interesting.
